Abstract
We study the existence and stability of persistent states in large networks of quadratic integrate-and-fire neurons. The networks consist of two popul ations, one excitatory and one inhibitory. The stability of the asynchronou s state is studied analytically. Our study demonstrates the role of recurre nt inhibition and inhibitory-inhibitory interactions in stable persistent a ctivity in large neuronal networks.
